Abstract:
A control device configured for use in a load control system to control an electrical load external to the control device may comprise an actuation member having a front surface defining a capacitive touch surface configured to detect a touch actuation along at least a portion of the front surface. The control device includes a main printed circuit board (PCB) comprising a control circuit, a tactile switch, a controllably conductive device, and a drive circuit operatively coupled to a control input of the controllably conductive device for rendering the controllably conductive device conductive or non-conductive to control the amount of power delivered to the electrical load. The control device also includes a capacitive touch PCB that comprises a touch sensitive circuit comprising one or more receiving capacitive touch pads located on the capacitive touch PCB and arranged in a linear array adjacent to the capacitive touch surface.
